Entering new registration rule when 500 rules already exist will delete an existing rule

When 500 registration rules exist, any newly created rule will wipe out the default rule or the last created rule, so that there are always only 500 rules.

This is fixed in ZLM 7.3 Interim Release 4 - see KB 7003346 "Updates to Novell ZENworks 7.3 Linux Management" which can be found at https://www.novell.com/support
